COUNTIES TO WATCH
Home to Jacksonville, Duval split almost evenly in 2016, 49% to Trump and 48% to Clinton. The county broke narrowly toward the Democrats in the state's extremely close 2018 Senate and governor contests.
Florida's largest county typically breaks Democratic, and is one major urban center in a battleground state where Hillary Clinton outperformed Barack Obama.
Obama carried Pinellas by a solid margin in each of his two runs, but in 2016, the county, home to St. Petersburg, turned in a near-even result.
This fast-growing county has been trending Democratic in recent cycles; population growth there could boost Democratic fortunes.
St. Lucie County
A swing county between Orlando and Miami, St. Lucie County tilted toward Trump in 2016 after Obama won it in both 2008 and 2012. The county broke for both Democratic candidates in the 2018 gubernatorial and Senate races.
